Machine Guided Learning
But researchers at Carnegie Mellon's Open Learning Initiative,
who've been experimenting with computer-based learning for
years, have found that when machine-guided learning is combined
with traditional classroom instruction, students can learn
material in half the time. Researchers at Ithaka S+R studied
two groups of students one group that received all instruction
in person, and another group that received a mixture of
traditional and computer-based instruction. The two groups did
equally well on tests, but those who received the computer
instruction were able to learn the same amount of material in
25 percent less time.
